Hey Team - I've had a couple of people report some pretty inconsistent
build failures on AppVeyor the last while. They all appear to be
(randomly) failing at the same spot in the build cycle. Below are a few
examples. There are more.

Unfortunately there isn't much to go in in the logs. We had this same
problem a couple of weeks ago and I've resurrected the email thread from
Owen (AppVeyor support staff) in hopes that he could provide some guidance
in my absence tomorrow.
